LOUIS H. BURCHETT, OF CASI-IION, OKLAHOMA.

VAPOR-LAMP.

To all whom 'it may concern:

Be it known that I, LOUIS H. Btmonn'r'r, a citizen of the United Statesof America, residing at Cashion, in the county of Kingfisher and Stateof Oklahoma, have invented new and useful Improvements in Vapor- Lanips,of which the following is a specification.

The invention relates to improvements in lamps and more particularly tothat class of lamps which utilize volatile liquids for fuel.

The invention has for one of its objects to provide a lamp of thischaracter which shall include a burner, a gas conducting tube connectedto the burner, and a generator tube for supplying the fuel to the gasconducting tube, the generator tube being adjustable toward and awayfrom the gas conducting tube so as to control the supply of air to theburner.

Another object of the present invention is to provide a lamp of thischaracter, which shall comprise a novel form of starting device, thelatter being supported by the generator and mounted below the same sothat the fuel in the generator tube may be initially heated before beingadmitted to the gas conducting tube, the starting device for thispurpose being provided with a cutoff whereby communication between thegenerator and the gas conducting tube is prevented when the startingdevice is positioned for operation.

With the above and other objects in view the invention consists in theconstruction, combination and arrangement of parts hereinafter set forthand falling within the scope of the appended claims.

In the accompanying drawings forming a part of the specification; Figure1 is a view in elevation of a lamp constructed in accordance with thepresent invention. Fig. 2 is a side view of the starting device showingthe same supported upon the generator tube. Fig. 3 is a fragmental viewillustrating the means of adjustment of the generator tube.

Similar reference characters designate like parts throughout the severalviews.

Referring more particularly to the accompanying drawings wherein I haveillus trated the preferred form of my invention, A designates a lampembodying the present invention and including a generator 13, gasconducting tube C and starting device D. The lamp comprises a burner 1,of any suitable or preferred construction, upon Specification of LettersPatent.

Patented Aug. 6, 1912. Serial No. 655,140.

which is mounted a cap 2 the latter being provided with a plurality ofapertures arranged concentrically about the cap, one of which is shownat 3 and an upturned marginal edge 1. Rigidly secured to the cap 2 andprojecting upwardly therefrom and above the burner 1 is a mantle support5 from which hangs a mantle (5, as is usual in burners of thisconstruction. The mantle 6 is preferably inclosed by a wire netting 7outside of which and concentric thereto is arranged a chimney 8, both ofthe members 7 and 8 being supported upon the cap 2, the chimney 8 forthis purpose engaging the upturned marginal edge -.t of the cap. Theburner 1 below the cap 2 is provided with threaded lateral openings 9and 10 respectively. Threadedly engaging the opening 9 of the burner isa gas conducting tube 11 which is preferably of substantially U-shapeand has its free end disposed above the plane of the burner. The opening10 of the burner, which is disposed diametrically opposite to theopening 9 therein, is designed to receive a curved supporting rod 12having a vertical arm 13 to which is secured a T-head 15. The horizontalportion of the head 15 is designed to receive the generator B arrangedin alinement with the upper end of the gas conducting tube 11 above theburner 1. At its discharge end the generator tube 16 of the generator Bis provided with a nipple 17 brazed or otherwise suitably fastenedthereto for the purpose of dirooting the fuel from the generator intothe gas conducting tube. At its opposite end the tube 16 exteriorly ofthe T-head 15 is connected to a supply valve 17 having a lateral nipple18 to which is connected a supply pipe 19. Intermediate the supply pipe19 and the valve 17 is positioned a filter 20 so that foreign matter maybe prevented from entering the burner.

For the purpose of adjusting the generator tube 16 of the generator Btoward and away from the gas receiving opening of the gas conductingtube 11, the horizontal portion of the T-head 15 is provided with a setscrew 21 which latter may be operated to release the gas conducting tubesufliciently to allow the same to be moved through the head 15 tocontrol the mixture in the gas conducting tube 11. After the properadjustment of the generator has been accomplished, the set screws may beoperated to retain the same in its adjusted position.

To initially vaporize the fuel in the generator B, I have provided thestarting device D which is supported by the generator tube 16, andcomprises a sleeve 22 having side portion cut out intermediate the endthereof as at 23 and provided upon its upper surface with a set screw24:SO that the same may be fastened in position on the tube, the cut-outportion permitting the tube 16 to be exposed to the flame as willpresently appear. Projecting upwardly from the sleeve 22 is a lug 25 towhich is pivotally secured a starting pan 26. The pan 26 is preferablymade of sheet metal and is connected at one end to a deflector orcut-off 27, the latter being rigidly secured to a lever 28 forming thepivotal connection for the pan. The pan 26 is provided with asbestos orsimilar packing 29 and is adapted to be swung on its pivot into aposition parallel with the generator tube, and in this position of thepan 26 it will be seen thatthe deflector 27 is arranged forwardly of thedischarge end of the generator tube thereby directing the fuel from thetube into the pan so that the same may be ignited to heat the generatorto vaporize the fuel in the generator tube, it being of courseunderstood thatthe valve 17 is opened slightly for this purpose. Uponthe generator tube being sufiiciently heated the fire in the pan 26 isextinguished and the latter swung about its pivot to assume a positionat right angles to the generator tube, and in this position of the panthe deflector 28 is out of the path of the fuel thereby permitting thelatter to enter the gas conducting tube 11 and the burner 1, the valve17 being opened to its full extent of movement upon the removal of thedeflector 28 from the mouth of the generator.

Medially of its length the gas conducting tube 11 is provided with acollar 30 which is secured thereto by means of a set screw 31. Thecollar 30 has a lateral. projecting ear 32 provided with an opening 33in which is mounted for swinging movement a supporting arm 34. The arm34 has an offset portion 35 spacedfrom the conducting tube 11 and screwthreaded for a portion of its length to receive a wind shield 36 whichmay be adjusted to any desired height and held in its adjusted positionby stop nuts 37 arranged upon the arm above and below the shield. Theshield 36 preferably comprises a metallic frame 38 designed to receive asection of glass or other suitable material 39, so that when the shieldis swung into position the light will be protected from drafts.

From the above description taken in connection with the accompanyingdrawings itwill be seen that I have provided a novel and eflicient vaporlamp wherein the generator may be adjusted toward and from the gasconducting tube so that the amount of air drawn into the conducting tubefrom the generator may be regulated to operate the light to the bestadvantage. It will also be noted that I have provided a very simple andefficient form of starting device whereby the gas in the generator tubemay be initially vaporized previous to feeding the burner, the moving ofthe starting device in its inoperative position serving to permit theflow of vaporized material through the conducting tube, thence to theburner.

Having thus described my invent-ion, what I claim and desire to secureby Letters-Patent. is:

1. In a vapor lamp, burner, a gas con ducting tube in communication withthe burner, a generator tube in communication with said gas conductingtube and spaced therefrom, a starting device, means associated with thestarting device and adapted to cut off communication between thegenerator tube and gas conducting tube in the operation of the startingdevice, and means for moving said starting device relatively to thegenerator tube.
